z claims. (c1. its-69) My invention relates to a metal window and has for its principal object the provision of a 'window wherein a plurality of metal sash, each carrying a glass panel, are mounted for simultaneous l swinging movement in a. metal frame, and such sash and frame having associated therewith means constructed of metal for imparting swinging movement to the sash, thus providing a construction that is entirely fire-proof.

i Further objects of my invention are to provide a metal window having a plurality of glazed sash that are burglar-proof by reason of the fact that the small size of the individual sash prevents an intruder from crawling through the opening in l5 the sash, even though the panel of glass is entirely removed therefrom; further, to' construct the window frame and the sash so as to effectively prevent rain from being blown by the window through the joints between the edges of the metal zo sash and the window frame. A

Further objects of my invention are to provide improved 'means for imparting swinging movement to the sash; further, to provide simple and eflicient means for securing the sash operating means so that the sash cannot be opened or closed from the exterior of the window; and, further, to provide a construction that will prevent the ingress of dust while the sash are closed.

With the foregoing and other objects in. view my invention consists in certain novel features of construction and arrangements of parts that will be hereinafter more fully described and claimed and illustrated in the accompanying drawing, in

which:

Fig. 1 is an elevational view of a metal window with parts broken away.

Fig. 2 is a vertical section taken on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged horizontal section taken on the line 3-3 of Fig. 1.

Fig. 4 is an enlarged horizontal section taken on the line 4-4 of Fig. l.

Fig. 5 is an enlarged horizontal section taken on the line 5-5 of Fig. 2.

Fig. 6 is an enlarged horizontal section taken on the line 6-6 of Fig. 1.

Fig. '7 is an elevational view of a rack and pinion construction that may be used for imparting swinging movement to the sash.

Fig. 8 is a side elevational view of the form of sash swinging mechanism seen in Fig. 7.

Referring by numerals to the accompanying drawing which illustrates a preferred embodiment of my invention, I0 designates the upper member of the window frame, which member is vsubstantially L-shaped in cross section, and the horizontal flange II of said member lies against the building wall at the top of the window opening and the vertical flange I2 lies against the outer face of the building wall just above the 5 window opening.

Vertically disposed side members of the window frame include outer flanges I3 that occupy the same plane with the anges I2 of top member I0, and said anges I3 overlie the outer face l0 of the building wall to the sides of the window opening. These upright members also include vertically disposed plates or anges I4 that lie against the faces of the building wall to the sides of the window opening to the rain, and said l5 plates or anges are connected tothe anges I3 by inclined plates I5.

The bottom member of the frame comprises an outer iiange I6 that occupies the same plane with the anges I2 and I3, and this ange I6 20 lies against the outer face of the building wall below the windowiopening therein. The lower member also includes a horizontally disposed plate or flange I1 that rests on top of the building wall at the bottom of the window opening 25 therein and connecting the plates or anges I6 and I1 is an inclined plate or ange I8. Formed integral with or xed to the underside of plate or flange II is a plate I9, and formed integral with and depending therefrom are spaced par. 30 allel flanges 20 and 2l.

Extending downwardly and outwardly from the front edge of plate I9 is an inclined plate or flange 22; Formed integral with or fixed to the inner faces of the upright side members of 35 the frame are inwardly presented parallel anges 23 and 24 which occupy the same planes respectively with the flanges 20 and 2I.

Formed integral with and projecting upwardly from plate or flange I1 are spaced parallel 40 ilanges 25 and 26 that occupy the same planes respectively with the fianges 20 and 23 and 2I and 24.

Where4 the window is provided with four swinging sash the anges 2l and- 26 are con- 45 nected by a vertically disposed bar 21 that occupies a point midway between the upright side members of the frame and connecting the intermediate portion of this vertically disposed bar with the anges 24 on the upright side members 5o are horizontally disposed bars 28.

Formed integral with or fixed to the upper edges of the horizontal bars 28 are outwardly and downwardly projecting flanges 29 that are parallel with the inclined flanges I8- and 22. Formed 55 integral with and secured to the outer face of the vertical bar are inclined plates or flanges ll against which the vertically disposed side members oi' the swinging sash are adapted to engage when the sash are closed.

Connected by suitable hinges 3| to the lower edge of the inclined flange or plate 22 are the inclined upper rails l2 of the sash frames and the upper faces of which rails are inclined so as to nt snugly against the under faces of the flangesv 22 whenthe sash are closed.

The upright side members or rails I8 of the sash frames are inclinedV so as to fit snugly against the inclined portions I5 of the upright side members of the window frame and against the inclined flanges I0 on rail 21 when the sash are closed.

I'he under faces of the lower rails 34 of the sash frames are inclined so as to fit snugly against the inclined plate 2l and the inclined portion Il of the lower window frame member when the sash are closed.

All of the sash frames are preferably formed of metal rails, the ends of which are welded to each other to provide integral structures.

It will be understood that the upper rails I2 of the upper sash in the window frame bear against the inclined flange 22st the top of the window structure and that the upper rails of the lower sash are hinged to the lower edge of the inclined flange 29 and bear against the underside of said inclined flange when the sash'are closed (see Fig. 2).

Arranged for vertical sliding movement on the inner face of the vertical bar 21 is a bar 35 in the upper and lower portions of which are formed slots 36, and passing through said slots and seated in the bar 21 are hinged pins or screws that retain the sliding bar against said bar 21.

Secured to the central part of the exposed face of the sliding bar 35 is a knob 38 that is utilized in raising and lowering said sliding bar.

Pivotally connected to the intermediate portions of the vertically disposed side members Il of the hinged sash are the lower ends of links I9, the upper ends thereof being secured to the sides of the sliding bar I5. As a result of this arrangement the sash will be swung outwardly into positions shown in dotted lines in Fig. 2, when the sliding bar 35 is moved downwardly, and when said bar is moved upwardly the sash will be simultaneously closed.

Knob 3l is provided with a threaded shank 40 in order that, after the sliding bar has been moved vertically in either direction, it'may be secured in its shifted position by tightening the knob so as to cause the inner end of the threaded' shank to engage with clamping pressure against the central portion of bar 21.

Removably positioned in the inner portion of the window frame and hearing against the flanges 2l, 28 and 25 is a metal frame carrying a metal screen 4|, the same being retained ln position within the frame by hooks 42 that are rotatably mounted in the upper and lowerraiis of the screen frame.' In Figs. 7 and 8, I have illustrated a simple and convenient means for swinging the sash upon their hinges and which means includes a vertically disposed rack bar 43 that is secured on the face of the lower portion of the sliding bar Il adjacent .one edge thereof.

Y Mounted on bar 21 adjacent the projecting portion of racky bar 42 is a plate 44 having bearings 45 in which is Journaied a shaft 4l and Secured on the latter is a worm wheel 41 and a pinion 4l that engages the teeth of rack bar 4I.

Projecting forwardly from the lower portion of plate 44 is a bracket 49 in which are Journaled the trunnions of a worm Il that engages the 5 worm wheel 41, and formed in the end of the exposedvtrunnion of this worm is a non-circular recess Il that is adapted to receive the non-circular end of a key or crank shaft l2 that is'utilized for rotating the worm.

Where this sash operating mechanism is used the rotation of worm il by the crank or key 52 imparts rotary movement to worm 41 and the pinion 4l and the latter engaging the teeth of rack 43 imparts longitudinal sliding movement 15 to bar Il.

Thus it will be seen that I have provided an all-metal and glass window that is relatively simple in construction, inexpensive of manufacture, and very eifective in performing the functions for which it is intended.

The size of the sash frames is such as to prevent burglars or intruders from entering the window after the glass in the sash has been broken, thus providing a burglar-proof construction.

Inasmuch as the outer edges of the rails or sash frames are inclined or bevelled and engage against correspondingly inclined or beveled faces on the window frame when the sash are closed, ingress of dust and rain blown by the wind through the window when the sash are closed is effectively prevented.

By providing suitable means for locking the sash to the window frame in closed position, my improved window may be advantageously used in jails, detention homes or other buildings where persons are connned. It will be understood that minor changes in the size, form and construction of the various parts of my improved metal window may be made and substituted for those herein shown and described without departing from the spirit of the invention, the scope of which is set forth in the appended claims.
